EchoSwitch Ultrasonic Multi-Point Level Switch

The general purpose ultrasonic switch provides non-contact level detection up to 26' or 8m with 3 relays. Each relay can be configured on a single set point alarm, automatic fill or empty including pump alternation or duplexing control, or two set points for out of bounds alarms. The switch is well suited for a broad range of corrosive, waste and slurry media, and is broadly selected for atmospheric day tank, process vessel, pump lift station and waste sump applications.

Features
  • Non-contact level detection with integral 3-channel relay control
  • Offered in four sensor ranges up to 8m with 1" and 2" transducers
  • EasyCal target push button calibration with non-volatile memory
  • 5cm minimum beam width for applications with restricted space
  • Fail-safe intelligence with troubleshooting diagnostic feedback
